About

The Resolution Copper project is a proposed underground mine 60 miles east of Phoenix, Arizona, near the town of Superior. The Arizona project is a joint venture owned by two global companies, Rio Tinto (55%) and BHP (45%).

The ore deposit lies nearly 7,000 feet below the earth’s surface. It represents one of the most significant untapped copper deposits today, with an estimated copper resource of 1.787 billion metric tonnes at an average grade of 1.5% copper.

We have strong community and regional support for the project, which has the potential to become one of the largest copper mines in America, add $1 billion a year to Arizona’s economy, and create thousands of local jobs in a region where mining has played an important role for more than a century.
